Question:medium
If \( y = f(x^2 + 2) \) and \( f'(3) = 5 \), then \( \frac{dy}{dx} \) at \( x = 1 \) is:
If \( y = f(x^2 + 2) \) and \( f'(3) = 5 \), then \( \frac{dy}{dx} \) at \( x = 1 \) is:
Show Hint
Always identify the "inner" function first. A common mistake is forgetting to multiply by the derivative of that inner part (\(2x\) in this case).
